Subject: [PATCH] tarantool: work around LeakSanitizer internal errors (#12321)

With enabled LeakSanitizer on AArch64 ICU build fails due to false
positive warnings from Leak Sanitizer (part of config.log):

```
configure:3209: checking whether we are cross compiling configure:3217: clang -o conftest -O1 -fno-omit-frame-pointer -gline-tables-only -DFUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION -fsanitize=address -fsanitize-address-use-after-scope -fsanitize=fuzzer-no-link  -lpthread conftest.c  >&5 configure:3221: $? = 0
configure:3228: ./conftest
==666==LeakSanitizer has encountered a fatal error. ==666==HINT: For debugging, try setting environment variable LSAN_OPTIONS=verbosity=1:log_threads=1 ==666==HINT: LeakSanitizer does not work under ptrace (strace, gdb, etc) configure:3232: $? = 1
configure:3239: error: in `/src/tarantool/build/icu': configure:3241: error: cannot run C compiled programs.
```

The patch disable LeakSanitizer on AArch64 and increase verbosity.
